Triethylamine → Methyl 8-(p-chlorophenylsulfonamido)-4-(2-methylsulfonyloxyethyl)-octanoate

Participants

Reaction Steps

A solution of 0.174 g of methyl 8-(p-chlorophenylsulfonamido)-4-(2-hydroxyethyl)octanoate in 2 ml methylene chloride is cooled to 0° and 0.1 ml of triethylamine is added followed by 0.042 ml of methylsulfonyl chloride. After 1 h, the reaction mixture is washed with saturated sodium bicarbonate and the organic layer is dried, filtered and evaporated to yield methyl 8-(p-chlorophenylsulfonamido)-4-(2-methylsulfonyloxyethyl)-octanoate as an oil.
